Str: 'str()' enchanced for data frames

Description

Enhanced 'str()': with variable numbers, row names and missing data indication

Usage

Str(df)

Arguments

df

Data frame

Details

'Str()' is an enhanced 'str()'. If the object is a data frame with atomic columns, this function captures output of internal 'str()', changes it and outputs the new one.

If the object is not a data frame or is a data frame with non-atomic columns, then output is not changed.

'Str()' (1) shows data frame structure with column indexes, (2) indicates presence of NA(s) with star (*) and (3) lists first five row names, if they are not default.

'Str()' does not work (therefore, passes everything back to common 'str()') with data frames which have non-atomic columns (fortunately, rare case).

Alternative: DescTools::Str() which uses cycles (slower!), has less features, but works with non-atomic columns.

Examples

# NOT RUN {
trees1 <- trees
row.names(trees1)[1] <- "a"
trees1[1, 1] <- NA
Str(trees)
Str(trees1)
# }
# NOT RUN {
trees.crazy <- trees
trees.crazy[[2]] <- trees[, 2, drop=FALSE]
Str(trees.crazy) # does not work with these crazy objects
# }
